ASSIGNOR, BY MESNE ASSIGNMENTS, TO

REMXNGTON TYPE'WRITER COMPANY, OF ILION, NElIV YORK, A CORPORATION OF NEW YORK TYPE-WRITING MACHINE.

Application filed January 18, 1913.

I '0 all US/win it may concern:

Be it known that l, rurrnun \V. SMITH, citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New Yorl-z and State of New York, have invented certain new and useful Improvements in Type-Writing chines, of which the following is a specilication.

My invention relates to severing devices for typewriting machines and its main object to provide improved devices ot the character specified. 1 i

Mo e specifically stated, the object of my invention is to provide a severing device for cutting at intervals continuous sheets or sti'ipisisti-ftll as tally strips, which it has been dillicult hereto-lore to cut clcanl; and etl'ecliivclz, the ordinary cutting blade or edge smm lweoming dull through use and resulting in a ragged or defective cutting of the paper.

To the above and other ends my invention consists in the 'l'eat-rcs of construction, com binations of devices and arrangements of parts hereinal ter described and particularly pointed out in the claims.

In carrying out my present invention "I arrange for cutting the sheet by a shearing cut, prmiding l'or this purpose two coiipcrating numbers or de\ lL'kS, one in the form of a slotted bar or plate and the other of a cutter or blade adapted to work transversely in this slot, the blade cooperating with the lace ol the bar and the edges of the slot to shear the paper. Normally the face of the slotted bar and the cutting edge of the blade are separated o provide a passageway or opening through which the paper or" 'Olli sheet passes, the blade being hinged at one end and provided with a linger piece at the opposite end, the construction enabling the blade to be swung against the paper and drawn through the slot in the bar to sever the paper. The bar remains stationary during the severing operation but is itself hinged or pivoted at thc, end opposite from the pivot ol' the blade and provided at its opposite. end with a linger piece and a holding device which normally retains it in lived position on its support. This hinging of the slotted bar is for the purpose of la.- cilitating the introduction of the paper into Specification of Letters Patent.

. the cutting blade.

-My invention will be explained in detail in connection with the accompanying drawing, wherein- Figure l is a fragmentary front elevation of a platen and platen carrier having my invention applied thereto; and Fig. 2 is a top plan view of the same.

As will be understood from the drawing, the platen carrier comprises a pair of par allel end bars 1, the right-hand bar only being illustrated, and connecting cross-bars 2 and 3. Said platen carrier provides a support for the axle l of a rotary platen which may comprise coaxial sections 5 and (3, of which the riglithand section may be em ployed as a'tally platen, being provided with feeding devices or rolls 7 and l'or facilitating the feeding of worksheets, such, for example, as l e narrow sheet or paper herein illustrated at 9 and which may be a tally strip. This tally strip is a long continuous sheet or ribbon and after being ad- .vanced upward at the front side of the rod "or 'ba r 3.

The novel severing device to which my invention primarily relates comprises a (cutting blade or member 1; and a slotted bar or member l l with which said blade cooperates. Said blade and said bar are mounted for relative movement, each being pivotally supported on the frame 11, 11, the pivots being at opposite ends from each other, so that such relative movement may lie obtained by moving one niembcr or the outer. The pivot for the cutting blade is a screw pivot 15 secured in the lel'tdrand plate 11. The body portion oithe blade extends horizontally substantially lengthwise of the platen above the rod 3 but its lefthand end portion lGis ollset foruard and slightly toward thelel't, being formed with a hole. which receives the shank ol the screw;

pivot 15. A restoring spring 17 is coiled around the screw 15 and anchored to the end plate 11, the opposite end being hooked around the olt-set 16.

has one end.

Said spring tends constantly to swing the blade 13 rearward on its pivot. As its righthand end portlon is approached the blade 13 is inclined forward at a slight angle to the body portion, as indicated at 1-?5, and atthe end of this inclined portion bends forward sharply at nearly right a-ngles as indicated at 19, passing through theslot in the slotted bar 11, thence bending sharply to the right forward of the slotted bar, as indicated at :21. The right-hand end of the portion 21 has secured to it a forwardly projecting finger piece or handle 32 by which the blade 13 may be conveniently manipulated. The right-hand end of the slot :20 terminates to the left of the linger piece 22, and the face of the bar 11 to the right of this slot provides a stop for cooperation with the portion 21 to limit the rearward swing of the blade 13 under the action of its spring 17 and to determine the normal position of said blade. The slotted bar 11 is vertically disposed forward of the cutting blade and so as to leave a passage-way or opening 23 between them through which the paper or work sheet 9 passes. In its passage the paper extends close to the rear face of the bar 14. The bar 11 may be provided at its top and bottom edges with forwardly inclined horizontal'lips or ledges 2-1, this construction being preferable as it promotes rigidity. The slot 20 is about midway between the lips 2t and is slightly wider than the thickness of the blade 13 and so that said blade 13 may be swung freely back and forth through it. The right-hand end of the bar 1% is provided with a forwardly extending horizontal ear 25 which receives a headed pivot screw 20, the said screw being secured in the right-hand end plate 11 and providing a support on which the bar is loosely pivoted at its right-hand end, the construction (enabling the bar to be swung up to some extent about its pivot. At its opposite or left-hand end the bar 1-1 is provided with a finger piece .27 which is in clined slightly rearward from the body portion of the bar. Just to the right ofthis linger piece the bar fits into or engages in a holding notch .or slot 28 formed vertically in the left-hand end plate 11. Secured to the front face of the bar 1 1 near its 'lelthand.

end as by rivets 29 is a detent tlUKlCU or spring finger or plate 30 which cXteuds lengthwise of the bar and may be shaped at its free end into a finger piece 511 as show u. As shown, the plate is cut or lrerled at its right-hand end in register with the slot 20. The tendency of this plate 30 is to swing forward away from the face of the bar and it is provided with a rounded lug 3:"! which is normally maintained by this tension or tendency in engagement with a hole or opening 33 formed in the front wall oli lhe slot or the notch 28. The construction is such.

that the re-action of the sprihg plate presses the bar 14 back against the rear n all of the notch 28, and said bar is locked or held normally in'a predetermined position in relationship to the notch by the engagement of the lug 32 with the hole 33. lly grasping and pressing the linger pieces 27 and 31 the lug is freed from the hole 33 so that the left end of the bar 14 may be swung up out of the notch and then. the bar may be swung forward on its pivot 26 [.0 a position such as that indicated by the dotted lines in Fig. 1; or even farther if desired, This forward swinging movement or the bar does not materially affect the blade 13 which remains substantially in normal position, and the construction enables the work sheet to be readily arranged between the bar and the blade or to be withdrawn, if desired. During the cutting or paper severin operations, however, the bar remains in normal position, being retained therein by the detent devices, the se\ering operation being performed by drawing the blade 13 forward through the slot 20, the blade being swung on its pivot to some such position as that illustrated by the dotted lines in Fig. The forward or cutting alge of the blade need not be sharpened but maybe substantially of the thickness of the body of the blade. The construction is such that the paper is sheared by the co-aetion between the forward edge of the blade and the edges of the slot or opening 2.0. The edge of the inclined portion 18 is first brought into cooperation with the right-hand er go 01 the paper and, after pressing the paper against the rear fare of the bar, gin-s an easy start to the cutting operation nhich. it is' apparent, will be a sliearil'- L,'- one and found in practice lo giro a clean and even cut and not an irregi tear as some-"mes happens here the suc, as o! the culling depends on the sharpness of the blade and where such blade has heroine dulled from use. The shearing operation in the present case is facilitated by the [act that the paper is held at opposite sides of lhe rooperating cutting element; in other words, the paper is held or retained aboie the cutting elements by the roller ll) and lr-"low said elements by the rollers and- 7 in roiiperation with the platen or section 5.

The rear upright face of the bar 1-1 pro-- been found in practice to be highly ellicient in ope ration.

Various changes may be mace Without departing from my invention.
